'DOUBLI'NG AND TWISTING MACHINE.

Specification of Letters Patent.

Patented Oct. 16, 1906.

To all whom it may concern.-

Be it known that we, WILLIAM GREGORY and CHARLES HEWITT, citizens of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Doubling and Twisting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to improvements in doubling and twisting machines, and has more particularly for its object to provide a device for the communication of differential movements to the spindle, flier-frame, and the bobbin, upon which the thread or fiber is wound; to do away with the necessity of rollers or drawing-rolls; to reduce the strain caused by doubling and twisting the threads or fibers in winding it upon the bobbin; to perform the act of doubling or twisting at the same time, and to provide means for a continuous and automatic lubrication of the spindle and the differential gear. We attain these objects by the mechanism illustrated in the accompanying drawings, in which similar numerals refer to similar parts throughout the several views, and in which Figure 1 is a vertical longitudinal section through the spindle, flier-frame, and differential gear, illustrating our invention. Fig. 2 is a cross-section view of tube and spindle on the line A A of Fig. 1, showing the oil-passages on each side of the spindle. Fig. 3 is a front elevation of a bobbin-carrying spindle With accompanying mechanical contrivances embodying our invention. Fig. 4 is a plan view of Fig. 3, and Fig. 5 is a further view illustrating our device for communicating the differential motion to the spindle and bobbin.

Referring to Fig. 1, 1 represents the lower portion of the spindle, 2 the threaded portion on which the flier-frame is screwed, and 3 the reduced upper portion of the spindle. The top of the spindle is made to snugly fit in the sleeve 5 and is provided with longitudinal grooves or gutters 4 for admitting oil to the chamber 23, which is formed in the sleeve 5 by reason of the reduced diameter of the spindle above. the screw-threaded portion2. The spindle may be driven by either band or belt, the device 6 having a conical cavity or interior, being formed for band or belt, as desired. A cone-shaped friction-clutch 7 is adapted to be engaged or disengaged with .or from the driving device 6 and is operated by a lever 7 which is shown in Fig. 3. The clutch 7 has a vertical internal groove or seat to receive and engage a key or feather 8 on the spindle, so as to communicate motion from the driving device 6 through the clutch I 7 to the spindle.

A stationary or non-rotating disk 9, having a depending hub and stop-pins and a boss 11, is carried by the spindle-support 26 27, and in the boss 11 is yieldingly supported the steel sleeve having an external thread.

The spiral sleeve 10 is prevented from turning by the screw 12, but is permitted a lateral motion to insure a meshof uniform depth with the spiral gear 15.

12* represents the opening in spiral 10 for the set-screw 12.

The sleeve 5 projects or extends above the top end of spindle Which fits uite snugly therein, and, as shown in Fig. 2 longitudinal grooves 4 in the upper portion of the spindle form oil-passages from above the spindle to all its operating parts and driving means. The sleeve 5 forms an oil-reservoir 23 around the spindle and is secured to the frame or bracket 13, into which the screw-threaded portion of the spindle is adapted to be secured. The gear 17 is fulcrumed to the bracket at 25. In a depending bracket of the frame 13 is mounted the common axis 14 of the connected toothed wheels 15 and 16, which may be fixed to said axis and turn therewith or may be connected and turn thereon, as desired. The wheel 15, that meshes with and rides on the spiral thread of the spiral sleeve 10, we prefer to call the spiral gear and the Wheels 16 and 17 meshing pinions for communicating rotary motion to the crown-gear 19 through the miter-gear 18.

On the upper portion 20 of the crown- I gear 19 is a bobbin-engaging pin 21 to cause a bobbin to turn around the sleeve 5 with the crown-gear 19.

A passage or opening is provided leading from the bottom of the oil-reservoir 23 and through the flier-frame 13 to hold a wick 24 or-the like for the purpose of carrying the oil to the spiral gear 15 and the spiral sleeve 10. From the surface of the disk 9 runs another oil-passage 28 for conducting oil to the lower portion of the spindle.

A circular guard-band 22 may be used, as shown, to protect the differential gear from dust and prevent the scatterin of oil, owing to the centrifugal action of the fiier.

. difliculty by providing a bobbin of peculiar The flier-frame is made to balance nicely the weight of the gearing carried by it. I

The differential result may be varied by changing the combination of gears to meet the desired requirements.

The spiral sleeve 10 is made of the best of steel, and fitting loosely in the boss 11 of the disk 9 it is allowed to follow the spindle and compensate for any wearing in the spindle or in the bearing in the disk. The wear we refer to will be all one way, owing to the pressure of the belt or band used for the purpose of driving the device, the object being to maintain the same depth of mesh substantially between the spiral sleeve 10 and the spiral gear 15, as this harmony would not exist should the spiral sleeve be-rigidly placed in any other way. I

The oil passes from the oil-chamber to the wick, which lies directly in the pathway of the spiral gear, and as the spindle and flier carrying the differential ear revolve the cen trifugal action constantI sprays the spiral gear and lubricates thespiral sleeve, any overflow of oil passing through the oil-passage in the disk 9 to the lower portion of the spindle. Thus a constant and automatic lubrication of the spindle and driving mechanism are provided for.

As the circumference of the-spiral sleeve is small, it forms an important factor where'a hi h rate of speed is desired.

In the operation of our spindle the fiierframe revolves with the spindle and the spiral gear meshing with the spiral sleeve receives a rotary motion in common with the pinion 16, which is mounted upon the same axis. The pinion 16 in turn communicates a rotary motion to the pinion 17, and it through its miter-gear 18 communicates a like motion to the crown-gear 19, which rotates the bob bin in an opposite direction to that traveled by the spindle and flier, but at a slower speed than that of the spindle and flier.

In other devices of this kind as the bobbin is filled with yarn it increases in circumference and draws more yarn per revolution, which changes the twist. We overcome this construction having but one head, which is conically formed and upon which the yarn is I laid layer after layer.

29 in Fig. 1 shows in dotted lines our new bobbin. The differential speed determines the amount of twist. The more the speeds differ the less the twist, and vice versa.

With this description of our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a doubling and twisting machine, a spindle, a bracket secured thereto and a spindle-support, in combination with an oil-receptacle surrounding the spindle, a yieldingly-supported externally threaded sleeve through which the spindle passes, carried by said support, a bobbin-carrier and means connecting-the said sleeve with the bobbincarrier to communicate a differential movement to the latter.

2. In a doubling and twisting machine, a spindle varying in circumference and provided with longitudinal grooves in its upper portion, in combination with a bracket securable thereto and carrying a tube or sleeve into which the spindle enters and which forms an oil-reservoir, substantially as set forth.

3. In a doubling and twisting machine, a spindle varying in circumference and provided with longitudinal grooves, in combination with a bracket securable thereto and revolubletherewith, a sleeve secured to said bracket and adapted to form an oil-reservoir about said spindle, a train of differential gears carried by said bracket, means for driving the same, and a wick or the like extending from said oil-reservoir into the pathway of the driving means, substantially as set forth.

4. In a doubling and twisting machine, a spindle varying in circumference and provided with longitudinal grooves on its upper portion, in combination with a bracket secured thereto, carrying a tube or sleeve into which the spindle enters, and also carryin a bobbin-carrier and a train of gears, and a spindle-support carrying an externallythreaded sleeve adapted to mesh with one of said gears to rotate said train of gears and communicate a differential movement to said bobbin-carrier.

In testimony whereof we affix our signatures in presence of two witnesses.
